Remember, always correct upstream issues prior to replacing a catalytic converter. For non-OBD II vehicles it is important to look at all readings on the smog check inspection report (VIR), including O2 & CO2. For 1996 & newer vehicles, always check the fuel trims. Fuel trims should be within 10%. One more thing, make sure that there are no vacuum or exhaust leaks in the system at the start of your diagnosis. Another easy method of determining the general health of a catalytic converter is to measure the inlet and outlet temperature of the converter. If the outlet temperature is less than the inlet temperature, the converter is not catalyzing properly and the converter is potentially defective. Please note that the Bureau of Automotive Repair does not accept the converter temperature test as a confirmed method of determining if a catalytic converter requires replacement.
Lastly, if your vehicle failed a smog check in California, you may qualify for the Consumer Assistance Program (CAP) and receive up to $1,200 in subsidized repairs.
Also, if your vehicle has failed a smog inspection or your vehicle is due for a smog inspection and it is likely to fail (ie the check engine light (MIL) is illuminated or the I/M Readiness monitors such as the CAT are incomplete), it is always a good idea to have a smog inspection done (and fail) before starting repairs. Diagnosis and repairs should be completed only at a licensed Smog Repair Station such as JUST SMOGS®+ in Huntington Beach. In the unfortunate event that you’ve spent $650 or more in emission related repairs and your vehicle still requires additional repairs or services to make it pass an inspection, you may qualify for a Repair Cost Waiver.
The Repair Cost Waiver, if approved by BAR, allows you to receive registration without a passing smog inspection. With the current high cost of catalytic converters, it is always a good idea to plan ahead with this option in mind.
